I am showing a webView as an alertDialog from a service when my app is not running on foreground, therefore, My webView is attached to the screen via WindowManager.addView() method.
The webView has an input field which I want to be accessible by the user. Unfortunately, when the user clicks on the input field, it is not showing the keyboard for users to allow input.
My webView is inside a cardView who's params are as follows:
public WindowManager.LayoutParams getParamsForOpenWebView() {
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.O) {
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.TYPE_PHONE,
WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM
| WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL
| WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH
| WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.START | Gravity.TOP;
params.x = left;
params.y = top;
return params;
} else {
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY,
WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM
| WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL
| WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH
| WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.START | Gravity.TOP;
params.x = left;
params.y = 200;
return params;
}
}
If I connect the phone to my laptop and use the laptop keyboard to add inputs to the input field, it works fine but it's just that the keyboard on the phone does not pop-up.
Also, the input is inside the webView therefore I cannot use View.requestFocus() to get focus unlike in case of an EditText.
I would really appreciate any help regarding how to request focus to the webView to allow inputs.
Found an answer to the question myself after a while.
I tried a lot of combinations of different flags but none worked, unless I tried
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL
| WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH
| WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS
These flags gave the results I wanted and hope it helps someone who goes through the same.

I'm using a transparent screenoverlay to detect when a user long presses the power key of their phone (or rather, when the shutdown option dialog appears), this is working fine.
Unfortunately, when this screenoverlay is active, the soft keyboard stops appearing and that is a problem for me. How can I prevent that?
The code I'm using is heavily based on this: Detect power button long press
public void warnOnShutdown() {
if (Settings.canDrawOverlays(this)) {
LinearLayout linearLayout = new LinearLayout(getApplicationContext()) {
public void onCloseSystemDialogs(String reason) {
if ("globalactions".equals(reason)) {
AntitheftStateManager.setShuttingDown(AntitheftService.this, true);
}
}
#Override
public boolean dispatchKeyEvent(KeyEvent event) {
return super.dispatchKeyEvent(event);
}
};
linearLayout.setFocusable(true);
View view = LayoutInflater.from(this).inflate(R.layout.system_overlay, linearLayout);
WindowManager windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
//params
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
100,
100,
WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL
| WindowManager.LayoutParams.FLAG_FULLSCREEN
| WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN
| WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.LEFT | Gravity.CENTER_VERTICAL;
windowManager.addView(view, params);
}
}
Layout:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="1dp"
android:layout_height="1dp"
android:orientation="vertical">
</LinearLayout>
Edit:
I should probably mention that the LinearLayout is attached to the window manager from a service, that means that the keyboard is not just blocked for my app, it's blocked for the whole phone as long as the service is running.
That's what happens when someone elses code is taken at face value. Turns out that changing the type from TYPE_SYSTEM_ALERT to TYPE_SYSTEM_OVERLAY solved my problem.
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
100,
100,
WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL
| WindowManager.LayoutParams.FLAG_FULLSCREEN
| WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN
| WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON,
PixelFormat.TRANSLUCENT);
I have window view in bottom and when i click on any edittext, keyboard opens but below windows view (Windowview comes over keyboard).
Tried using adjustPan, adjustResize.
Tried using show hide the view as per keyboard visibility but it give Security Exception.
mTabParams = new WindowManager.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.TYPE_SYSTEM_ALERT |
WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
PixelFormat.TRANSPARENT);
mTabParams.format = PixelFormat.TRANSLUCENT;
mTabParams.height = TAB_BAR_HEIGHT;
mTabParams.gravity = Gravity.BOTTOM;
mWindowmanager = (WindowManager) getSystemService(Context.WINDOW_SERVICE);
mWindowmanager.addView(mTabbarLayout, mTabParams);
This worked for me :
params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_PRIORITY_PHONE,
WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN |
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
WindowManager.LayoutParams.FLAG_SPLIT_TOUCH |
WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM,
PixelFormat.TRANSLUCENT);
This put the added view behind the keyboard.
I'm showing a custom overlay with this parameter inflating the view from a service:
params = new WindowManager.LayoutParams(WindowManager
.LayoutParams
.MATCH_PARENT,
statusBarHeight, WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY, WindowManager
.LayoutParams.FLAG_NOT_TOUCH_MODAL | WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN
| WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE | WindowManager.LayoutParams
.FLAG_NOT_FOCUSABLE, 0);
params.gravity = Gravity.CENTER | Gravity.TOP;
The problem is that if the status bar is expanded, the overlay is over the quick settings menu. How can I avoid that? I'm using android 6.
Instead of TYPE_SYSTEM_OVERLAY use TYPE_SYSTEM_ERROR.
params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.MATCH_PARENT,
100,
// Allows the view to be on top of the StatusBar
WindowManager.LayoutParams.TYPE_SYSTEM_ERROR,
// Keeps the button presses from going to the background window
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
// Enables the notification to recieve touch events
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
// Draws over status bar
WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.TOP|Gravity.CENTER;
mWindowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
mWindowManager.addView(mView, mLP);
This should solve your issue.
Pretty simple: I add a dynamic button on screen and I try to fade it out after adding, but the animation never plays. I tried adding it later when it is already rendered on the screen, but still nothing. Below is the code:
btn = new ImageButton(context);
btn.setBackgroundColor(0xFFFF0000);
params = new WindowManager.LayoutParams(
width,height,
WindowManager.LayoutParams.TYPE_SYSTEM_ALERT |
WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH |
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.TOP | Gravity.LEFT;
windowManager.addView(btn, params);
btn.startAnimation(new AlphaAnimation(1,0));
Any ideas?
Try this:
btn.setAlpha(0f);
btn.animate().alpha(1).setDuration(1000);
This answer may explain why you're getting such strange behavior if you've set the alpha to 0 in xml.
I made a View in service which runs always on top of every application in android.
Initially, the behaviour of service is TYPE_SYSTEM_ALERT .
WindowManager.LayoutParams layparams = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,
WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
PixelFormat.TRANSLUCENT);
layparams .gravity = Gravity.CENTER_VERTICAL| Gravity.CENTER_HORIZONTAL;
wm = (WindowManager) getSystemService(WINDOW_SERVICE);
wm.addView(serviceView, layparams );
I am changing the behaviour of service at run time means switching between TYPE_SYSTEM_ALERT AND TYPE_SYSTEM_OVERLAY on touch. Switch take place when I touch outside the view parameters and when touch inside the view parameters.
layparams .type = WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY;
Using updateViewLayout(serviceView, layparams )
PROBLEM: Is when I touch outside of view , the first touch just activate TYPE_SYSTEM_OVERLAY and after then outside app works fine. When TYPE_SYSTEM_OVERLAY is working , after that when you touch within the view it will trigger the action of object behind the view not the action of the view. But when u once touch the view TYPE_SYSTEM_ALERT will be applied and now the View will behave normally .
Current Implementation : I have to touch twice to work that particular thing when switch take place between layout parameters.
use this one... works perfectly on ICS and above
params.type = WindowManager.LayoutParams.TYPE_SYSTEM_ERROR;//This one is necessary.
params.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH |
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS;
params.gravity = Gravity.TOP | Gravity.RIGHT;
params.x = 0;
params.y = -params.height;
windowManager.addView(tile, params);
you can do this by calling updateViewLayout() on instance of WindowManager class.
wm = (WindowManager) getSystemService(WINDOW_SERVICE);
// create new layout params
WindowManager.LayoutParams newlayparams = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
PixelFormat.TRANSLUCENT);
//update new layout
wm.updateViewLayout(serviceView, newlayparams);
Hope it help!
